Instance Method Details

Adds a permission to the resource policy associated with the specified
AWS Lambda function. You use resource policies to grant permissions to
event sources that use push model. In a push model, event sources
(such as Amazon S3 and custom applications) invoke your Lambda
function. Each permission you add to the resource policy allows an
event source, permission to invoke the Lambda function.

If you are using versioning, the permissions you add are specific to
the Lambda function version or alias you specify in the
AddPermission request via the Qualifier parameter. For more
information about versioning, see AWS Lambda Function Versioning and
Aliases.

This operation requires permission for the lambda:AddPermission
action.

Examples:

Example: add-permission

# This example adds a permission for an S3 bucket to invoke a Lambda function.
resp=client.add_permission({action:"lambda:InvokeFunction",function_name:"MyFunction",principal:"s3.amazonaws.com",source_account:"123456789012",source_arn:"arn:aws:s3:::examplebucket/*",statement_id:"ID-1",})resp.to_houtputsthefollowing:{statement:"ID-1",}

Name of the Lambda function whose resource policy you are updating by
adding a new permission.

You can specify a function name (for example, Thumbnail) or you can
specify Amazon Resource Name (ARN) of the function (for example,
arn:aws:lambda:us-west-2:account-id:function:ThumbNail). AWS Lambda
also allows you to specify partial ARN (for example,
account-id:Thumbnail). Note that the length constraint applies only
to the ARN. If you specify only the function name, it is limited to 64
characters in length.

:statement_id(required, String)
—

A unique statement identifier.

:action(required, String)
—

The AWS Lambda action you want to allow in this statement. Each Lambda
action is a string starting with lambda: followed by the API name .
For example, lambda:CreateFunction. You can use wildcard
(lambda:*) to grant permission for all AWS Lambda actions.

:principal(required, String)
—

The principal who is getting this permission. It can be Amazon S3
service Principal (s3.amazonaws.com) if you want Amazon S3 to invoke
the function, an AWS account ID if you are granting cross-account
permission, or any valid AWS service principal such as
sns.amazonaws.com. For example, you might want to allow a custom
application in another AWS account to push events to AWS Lambda by
invoking your function.

:source_arn(String)
—

This is optional; however, when granting permission to invoke your
function, you should specify this field with the Amazon Resource Name
(ARN) as its value. This ensures that only events generated from the
specified source can invoke the function.

If you add a permission without providing the source ARN, any AWS
account that creates a mapping to your function ARN can send events to
invoke your Lambda function.

:source_account(String)
—

This parameter is used for S3 and SES. The AWS account ID (without a
hyphen) of the source owner. For example, if the SourceArn
identifies a bucket, then this is the bucket owner's account ID. You
can use this additional condition to ensure the bucket you specify is
owned by a specific account (it is possible the bucket owner deleted
the bucket and some other AWS account created the bucket). You can
also use this condition to specify all sources (that is, you don't
specify the SourceArn) owned by a specific account.

:event_source_token(String)
—

A unique token that must be supplied by the principal invoking the
function. This is currently only used for Alexa Smart Home functions.

:qualifier(String)
—

You can use this optional query parameter to describe a qualified ARN
using a function version or an alias name. The permission will then
apply to the specific qualified ARN. For example, if you specify
function version 2 as the qualifier, then permission applies only when
request is made using qualified function ARN:

arn:aws:lambda:aws-region:acct-id:function:function-name:2

If you specify an alias name, for example PROD, then the permission
is valid only for requests made using the alias ARN:

arn:aws:lambda:aws-region:acct-id:function:function-name:PROD

If the qualifier is not specified, the permission is valid only when
requests is made using unqualified function ARN.

Name of the Lambda function for which you want to create an alias.
Note that the length constraint applies only to the ARN. If you
specify only the function name, it is limited to 64 characters in
length.

Identifies a stream as an event source for a Lambda function. It can
be either an Amazon Kinesis stream or an Amazon DynamoDB stream. AWS
Lambda invokes the specified function when records are posted to the
stream.

This association between a stream source and a Lambda function is
called the event source mapping.

This event source mapping is relevant only in the AWS Lambda pull
model, where AWS Lambda invokes the function. For more information,
see AWS Lambda: How it Works in the AWS Lambda Developer Guide.

You provide mapping information (for example, which stream to read
from and which Lambda function to invoke) in the request body.

Each event source, such as an Amazon Kinesis or a DynamoDB stream, can
be associated with multiple AWS Lambda function. A given Lambda
function can be associated with multiple AWS event sources.

The Amazon Resource Name (ARN) of the Amazon Kinesis or the Amazon
DynamoDB stream that is the event source. Any record added to this
stream could cause AWS Lambda to invoke your Lambda function, it
depends on the BatchSize. AWS Lambda POSTs the Amazon Kinesis event,
containing records, to your Lambda function as JSON.

:function_name(required, String)
—

The Lambda function to invoke when AWS Lambda detects an event on the
stream.

You can specify the function name (for example, Thumbnail) or you
can specify Amazon Resource Name (ARN) of the function (for example,
arn:aws:lambda:us-west-2:account-id:function:ThumbNail).

If you are using versioning, you can also provide a qualified function
ARN (ARN that is qualified with function version or alias name as
suffix). For more information about versioning, see AWS Lambda
Function Versioning and Aliases

AWS Lambda also allows you to specify only the function name with the
account ID qualifier (for example, account-id:Thumbnail).

Note that the length constraint applies only to the ARN. If you
specify only the function name, it is limited to 64 characters in
length.

The largest number of records that AWS Lambda will retrieve from your
event source at the time of invoking your function. Your function
receives an event with all the retrieved records. The default is 100
records.

:starting_position(required, String)
—

The position in the stream where AWS Lambda should start reading.
Valid only for Kinesis streams. For more information, see
ShardIteratorType in the Amazon Kinesis API Reference.

:starting_position_timestamp(Time, DateTime, Date, Integer, String)
—

The timestamp of the data record from which to start reading. Used
with shard iterator type AT_TIMESTAMP. If a record with this
exact timestamp does not exist, the iterator returned is for the next
(later) record. If the timestamp is older than the current trim
horizon, the iterator returned is for the oldest untrimmed data record
(TRIM_HORIZON). Valid only for Kinesis streams.

Creates a new Lambda function. The function metadata is created from
the request parameters, and the code for the function is provided by a
.zip file in the request body. If the function name already exists,
the operation will fail. Note that the function name is
case-sensitive.

If you are using versioning, you can also publish a version of the
Lambda function you are creating using the Publish parameter. For
more information about versioning, see AWS Lambda Function Versioning
and Aliases.

This operation requires permission for the lambda:CreateFunction
action.

Examples:

Example: create-function

# This example creates a Lambda function.
resp=client.create_function({code:{},description:"",function_name:"MyFunction",handler:"souce_file.handler_name",# is of the form of the name of your source file and then name of your function handler
memory_size:128,publish:true,role:"arn:aws:iam::123456789012:role/service-role/role-name",# replace with the actual arn of the execution role you created
runtime:"nodejs4.3",timeout:15,vpc_config:{},})resp.to_houtputsthefollowing:{code_sha_256:"",code_size:123,description:"",function_arn:"arn:aws:lambda:us-west-2:123456789012:function:MyFunction",function_name:"MyFunction",handler:"source_file.handler_name",last_modified:Time.parse("2016-11-21T19:49:20.006+0000"),memory_size:128,role:"arn:aws:iam::123456789012:role/service-role/role-name",runtime:"nodejs4.3",timeout:123,version:"1",vpc_config:{},}

The name you want to assign to the function you are uploading. The
function names appear in the console and are returned in the
ListFunctions API. Function names are used to specify functions to
other AWS Lambda API operations, such as Invoke. Note that the length
constraint applies only to the ARN. If you specify only the function
name, it is limited to 64 characters in length.

:runtime(required, String)
—

The runtime environment for the Lambda function you are uploading.

To use the Python runtime v3.6, set the value to "python3.6". To use
the Python runtime v2.7, set the value to "python2.7". To use the
Node.js runtime v6.10, set the value to "nodejs6.10". To use the
Node.js runtime v4.3, set the value to "nodejs4.3".

Node v0.10.42 is currently marked as deprecated. You must migrate
existing functions to the newer Node.js runtime versions available on
AWS Lambda (nodejs4.3 or nodejs6.10) as soon as possible. You can
request a one-time extension until June 30, 2017 by going to the
Lambda console and following the instructions provided. Failure to do
so will result in an invalid parmaeter error being returned. Note that
you will have to follow this procedure for each region that contains
functions written in the Node v0.10.42 runtime.

:role(required, String)
—

The Amazon Resource Name (ARN) of the IAM role that Lambda assumes
when it executes your function to access any other Amazon Web Services
(AWS) resources. For more information, see AWS Lambda: How it
Works.

:handler(required, String)
—

The function within your code that Lambda calls to begin execution.
For Node.js, it is the module-name.export value in your function.
For Java, it can be package.class-name::handler or
package.class-name. For more information, see Lambda Function
Handler (Java).

A short, user-defined function description. Lambda does not use this
value. Assign a meaningful description as you see fit.

:timeout(Integer)
—

The function execution time at which Lambda should terminate the
function. Because the execution time has cost implications, we
recommend you set this value based on your expected execution time.
The default is 3 seconds.

:memory_size(Integer)
—

The amount of memory, in MB, your Lambda function is given. Lambda
uses this memory size to infer the amount of CPU and memory allocated
to your function. Your function use-case determines your CPU and
memory requirements. For example, a database operation might need less
memory compared to an image processing function. The default value is
128 MB. The value must be a multiple of 64 MB.

:publish(Boolean)
—

This boolean parameter can be used to request AWS Lambda to create the
Lambda function and publish a version as an atomic operation.

If your Lambda function accesses resources in a VPC, you provide this
parameter identifying the list of security group IDs and subnet IDs.
These must belong to the same VPC. You must provide at least one
security group and one subnet ID.

The Lambda function name for which the alias is created. Deleting an
alias does not delete the function version to which it is pointing.
Note that the length constraint applies only to the ARN. If you
specify only the function name, it is limited to 64 characters in
length.

#delete_function(params = {}) ⇒ Struct

Deletes the specified Lambda function code and configuration.

If you are using the versioning feature and you don't specify a
function version in your DeleteFunction request, AWS Lambda will
delete the function, including all its versions, and any aliases
pointing to the function versions. To delete a specific function
version, you must provide the function version via the Qualifier
parameter. For information about function versioning, see AWS Lambda
Function Versioning and Aliases.

When you delete a function the associated resource policy is also
deleted. You will need to delete the event source mappings explicitly.

This operation requires permission for the lambda:DeleteFunction
action.

You can specify the function name (for example, Thumbnail) or you
can specify Amazon Resource Name (ARN) of the function (for example,
arn:aws:lambda:us-west-2:account-id:function:ThumbNail). If you are
using versioning, you can also provide a qualified function ARN (ARN
that is qualified with function version or alias name as suffix). AWS
Lambda also allows you to specify only the function name with the
account ID qualifier (for example, account-id:Thumbnail). Note that
the length constraint applies only to the ARN. If you specify only the
function name, it is limited to 64 characters in length.

:qualifier(String)
—

Using this optional parameter you can specify a function version (but
not the $LATEST version) to direct AWS Lambda to delete a specific
function version. If the function version has one or more aliases
pointing to it, you will get an error because you cannot have aliases
pointing to it. You can delete any function version but not the
$LATEST, that is, you cannot specify $LATEST as the value of this
parameter. The $LATEST version can be deleted only when you want to
delete all the function versions and aliases.

You can only specify a function version, not an alias name, using this
parameter. You cannot delete a function version using its alias.

If you don't specify this parameter, AWS Lambda will delete the
function, including all of its versions and aliases.

You can use this operation to retrieve Lambda limits information, such
as code size and concurrency limits. For more information about
limits, see AWS Lambda Limits. You can also retrieve resource
usage statistics, such as code storage usage and function count.

Function name for which the alias is created. An alias is a
subresource that exists only in the context of an existing Lambda
function so you must specify the function name. Note that the length
constraint applies only to the ARN. If you specify only the function
name, it is limited to 64 characters in length.

Returns the configuration information of the Lambda function and a
presigned URL link to the .zip file you uploaded with CreateFunction
so you can download the .zip file. Note that the URL is valid for up
to 10 minutes. The configuration information is the same information
you provided as parameters when uploading the function.

Using the optional Qualifier parameter, you can specify a specific
function version for which you want this information. If you don't
specify this parameter, the API uses unqualified function ARN which
return information about the $LATEST version of the Lambda function.
For more information, see AWS Lambda Function Versioning and
Aliases.

You can specify a function name (for example, Thumbnail) or you can
specify Amazon Resource Name (ARN) of the function (for example,
arn:aws:lambda:us-west-2:account-id:function:ThumbNail). AWS Lambda
also allows you to specify a partial ARN (for example,
account-id:Thumbnail). Note that the length constraint applies only
to the ARN. If you specify only the function name, it is limited to 64
characters in length.

:qualifier(String)
—

Using this optional parameter to specify a function version or an
alias name. If you specify function version, the API uses qualified
function ARN for the request and returns information about the
specific Lambda function version. If you specify an alias name, the
API uses the alias ARN and returns information about the function
version to which the alias points. If you don't provide this
parameter, the API uses unqualified function ARN and returns
information about the $LATEST version of the Lambda function.

Returns the configuration information of the Lambda function. This the
same information you provided as parameters when uploading the
function by using CreateFunction.

If you are using the versioning feature, you can retrieve this
information for a specific function version by using the optional
Qualifier parameter and specifying the function version or alias
that points to it. If you don't provide it, the API returns
information about the $LATEST version of the function. For more
information about versioning, see AWS Lambda Function Versioning and
Aliases.

This operation requires permission for the
lambda:GetFunctionConfiguration operation.

The name of the Lambda function for which you want to retrieve the
configuration information.

You can specify a function name (for example, Thumbnail) or you can
specify Amazon Resource Name (ARN) of the function (for example,
arn:aws:lambda:us-west-2:account-id:function:ThumbNail). AWS Lambda
also allows you to specify a partial ARN (for example,
account-id:Thumbnail). Note that the length constraint applies only
to the ARN. If you specify only the function name, it is limited to 64
characters in length.

:qualifier(String)
—

Using this optional parameter you can specify a function version or an
alias name. If you specify function version, the API uses qualified
function ARN and returns information about the specific function
version. If you specify an alias name, the API uses the alias ARN and
returns information about the function version to which the alias
points.

If you don't specify this parameter, the API uses unqualified
function ARN, and returns information about the $LATEST function
version.

Returns the resource policy associated with the specified Lambda
function.

If you are using the versioning feature, you can get the resource
policy associated with the specific Lambda function version or alias
by specifying the version or alias name using the Qualifier
parameter. For more information about versioning, see AWS Lambda
Function Versioning and Aliases.

You can specify the function name (for example, Thumbnail) or you
can specify Amazon Resource Name (ARN) of the function (for example,
arn:aws:lambda:us-west-2:account-id:function:ThumbNail). If you are
using versioning, you can also provide a qualified function ARN (ARN
that is qualified with function version or alias name as suffix). AWS
Lambda also allows you to specify only the function name with the
account ID qualifier (for example, account-id:Thumbnail). Note that
the length constraint applies only to the ARN. If you specify only the
function name, it is limited to 64 characters in length.

:qualifier(String)
—

You can specify this optional query parameter to specify a function
version or an alias name in which case this API will return all
permissions associated with the specific qualified ARN. If you don't
provide this parameter, the API will return permissions that apply to
the unqualified function ARN.

If you are using the versioning feature, you can invoke the specific
function version by providing function version or alias name that is
pointing to the function version using the Qualifier parameter in
the request. If you don't provide the Qualifier parameter, the
$LATEST version of the Lambda function is invoked. Invocations occur
at least once in response to an event and functions must be idempotent
to handle this. For information about the versioning feature, see AWS
Lambda Function Versioning and Aliases.

This operation requires permission for the lambda:InvokeFunction
action.

You can specify a function name (for example, Thumbnail) or you can
specify Amazon Resource Name (ARN) of the function (for example,
arn:aws:lambda:us-west-2:account-id:function:ThumbNail). AWS Lambda
also allows you to specify a partial ARN (for example,
account-id:Thumbnail). Note that the length constraint applies only
to the ARN. If you specify only the function name, it is limited to 64
characters in length.

:invocation_type(String)
—

By default, the Invoke API assumes RequestResponse invocation
type. You can optionally request asynchronous execution by specifying
Event as the InvocationType. You can also use this parameter to
request AWS Lambda to not execute the function but do some
verification, such as if the caller is authorized to invoke the
function and if the inputs are valid. You request this by specifying
DryRun as the InvocationType. This is useful in a cross-account
scenario when you want to verify access to a function without running
it.

:log_type(String)
—

You can set this optional parameter to Tail in the request only if
you specify the InvocationType parameter with value
RequestResponse. In this case, AWS Lambda returns the base64-encoded
last 4 KB of log data produced by your Lambda function in the
x-amz-log-result header.

:client_context(String)
—

Using the ClientContext you can pass client-specific information to
the Lambda function you are invoking. You can then process the client
information in your Lambda function as you choose through the context
variable. For an example of a ClientContext JSON, see PutEvents
in the Amazon Mobile Analytics API Reference and User Guide.

The ClientContext JSON must be base64-encoded.

:payload(String, IO)
—

JSON that you want to provide to your Lambda function as input.

:qualifier(String)
—

You can use this optional parameter to specify a Lambda function
version or alias name. If you specify a function version, the API uses
the qualified function ARN to invoke a specific Lambda function. If
you specify an alias name, the API uses the alias ARN to invoke the
Lambda function version to which the alias points.

If you don't provide this parameter, then the API uses unqualified
function ARN which results in invocation of the $LATEST version.

Submits an invocation request to AWS Lambda. Upon receiving the
request, Lambda executes the specified function asynchronously. To see
the logs generated by the Lambda function execution, see the
CloudWatch Logs console.

This operation requires permission for the lambda:InvokeFunction
action.

Returns list of aliases created for a Lambda function. For each alias,
the response includes information such as the alias ARN, description,
alias name, and the function version to which it points. For more
information, see Introduction to AWS Lambda Aliases.

Lambda function name for which the alias is created. Note that the
length constraint applies only to the ARN. If you specify only the
function name, it is limited to 64 characters in length.

:function_version(String)
—

If you specify this optional parameter, the API returns only the
aliases that are pointing to the specific Lambda function version,
otherwise the API returns all of the aliases created for the Lambda
function.

:marker(String)
—

Optional string. An opaque pagination token returned from a previous
ListAliases operation. If present, indicates where to continue the
listing.

:max_items(Integer)
—

Optional integer. Specifies the maximum number of aliases to return in
response. This parameter value must be greater than 0.

Returns a list of event source mappings you created using the
CreateEventSourceMapping (see CreateEventSourceMapping).

For each mapping, the API returns configuration information. You can
optionally specify filters to retrieve specific event source mappings.

If you are using the versioning feature, you can get list of event
source mappings for a specific Lambda function version or an alias as
described in the FunctionName parameter. For information about the
versioning feature, see AWS Lambda Function Versioning and
Aliases.

This operation requires permission for the
lambda:ListEventSourceMappings action.

The Amazon Resource Name (ARN) of the Amazon Kinesis stream. (This
parameter is optional.)

:function_name(String)
—

The name of the Lambda function.

You can specify the function name (for example, Thumbnail) or you
can specify Amazon Resource Name (ARN) of the function (for example,
arn:aws:lambda:us-west-2:account-id:function:ThumbNail). If you are
using versioning, you can also provide a qualified function ARN (ARN
that is qualified with function version or alias name as suffix). AWS
Lambda also allows you to specify only the function name with the
account ID qualifier (for example, account-id:Thumbnail). Note that
the length constraint applies only to the ARN. If you specify only the
function name, it is limited to 64 characters in length.

:marker(String)
—

Optional string. An opaque pagination token returned from a previous
ListEventSourceMappings operation. If present, specifies to continue
the list from where the returning call left off.

:max_items(Integer)
—

Optional integer. Specifies the maximum number of event sources to
return in response. This value must be greater than 0.

Function name whose versions to list. You can specify a function name
(for example, Thumbnail) or you can specify Amazon Resource Name
(ARN) of the function (for example,
arn:aws:lambda:us-west-2:account-id:function:ThumbNail). AWS Lambda
also allows you to specify a partial ARN (for example,
account-id:Thumbnail). Note that the length constraint applies only
to the ARN. If you specify only the function name, it is limited to 64
characters in length.

:marker(String)
—

Optional string. An opaque pagination token returned from a previous
ListVersionsByFunction operation. If present, indicates where to
continue the listing.

:max_items(Integer)
—

Optional integer. Specifies the maximum number of AWS Lambda function
versions to return in response. This parameter value must be greater
than 0.

Publishes a version of your function from the current snapshot of
$LATEST. That is, AWS Lambda takes a snapshot of the function code and
configuration information from $LATEST and publishes a new version.
The code and configuration cannot be modified after publication. For
information about the versioning feature, see AWS Lambda Function
Versioning and Aliases.

Examples:

Example: To publish a version of a Lambda function

# This operation publishes a version of a Lambda function
resp=client.publish_version({code_sha_256:"",description:"",function_name:"myFunction",})resp.to_houtputsthefollowing:{code_sha_256:"",code_size:123,description:"",function_arn:"arn:aws:lambda:us-west-2:123456789012:function:myFunction",function_name:"myFunction",handler:"index.handler",last_modified:Time.parse("2016-11-21T19:49:20.006+0000"),memory_size:128,role:"arn:aws:iam::123456789012:role/lambda_basic_execution",runtime:"python2.7",timeout:123,version:"1",vpc_config:{},}

The Lambda function name. You can specify a function name (for
example, Thumbnail) or you can specify Amazon Resource Name (ARN) of
the function (for example,
arn:aws:lambda:us-west-2:account-id:function:ThumbNail). AWS Lambda
also allows you to specify a partial ARN (for example,
account-id:Thumbnail). Note that the length constraint applies only
to the ARN. If you specify only the function name, it is limited to 64
characters in length.

:code_sha_256(String)
—

The SHA256 hash of the deployment package you want to publish. This
provides validation on the code you are publishing. If you provide
this parameter value must match the SHA256 of the $LATEST version for
the publication to succeed.

:description(String)
—

The description for the version you are publishing. If not provided,
AWS Lambda copies the description from the $LATEST version.

#remove_permission(params = {}) ⇒ Struct

You can remove individual permissions from an resource policy
associated with a Lambda function by providing a statement ID that you
provided when you added the permission.

If you are using versioning, the permissions you remove are specific
to the Lambda function version or alias you specify in the
AddPermission request via the Qualifier parameter. For more
information about versioning, see AWS Lambda Function Versioning and
Aliases.

Note that removal of a permission will cause an active event source to
lose permission to the function.

You can specify a function name (for example, Thumbnail) or you can
specify Amazon Resource Name (ARN) of the function (for example,
arn:aws:lambda:us-west-2:account-id:function:ThumbNail). AWS Lambda
also allows you to specify a partial ARN (for example,
account-id:Thumbnail). Note that the length constraint applies only
to the ARN. If you specify only the function name, it is limited to 64
characters in length.

:statement_id(required, String)
—

Statement ID of the permission to remove.

:qualifier(String)
—

You can specify this optional parameter to remove permission
associated with a specific function version or function alias. If you
don't specify this parameter, the API removes permission associated
with the unqualified function ARN.

#tag_resource(params = {}) ⇒ Struct

Creates a list of tags (key-value pairs) on the Lambda function.
Requires the Lambda function ARN (Amazon Resource Name). If a key is
specified without a value, Lambda creates a tag with the specified key
and a value of null.

You can update an event source mapping. This is useful if you want to
change the parameters of the existing mapping without losing your
position in the stream. You can change which function will receive the
stream records, but to change the stream itself, you must create a new
mapping.

If you are using the versioning feature, you can update the event
source mapping to map to a specific Lambda function version or alias
as described in the FunctionName parameter. For information about
the versioning feature, see AWS Lambda Function Versioning and
Aliases.

If you disable the event source mapping, AWS Lambda stops polling. If
you enable again, it will resume polling from the time it had stopped
polling, so you don't lose processing of any records. However, if you
delete event source mapping and create it again, it will reset.

This operation requires permission for the
lambda:UpdateEventSourceMapping action.

You can specify a function name (for example, Thumbnail) or you can
specify Amazon Resource Name (ARN) of the function (for example,
arn:aws:lambda:us-west-2:account-id:function:ThumbNail). AWS Lambda
also allows you to specify a partial ARN (for example,
account-id:Thumbnail). Note that the length constraint applies only
to the ARN. If you specify only the function name, it is limited to 64
characters in length.

If you are using versioning, you can also provide a qualified function
ARN (ARN that is qualified with function version or alias name as
suffix). For more information about versioning, see AWS Lambda
Function Versioning and Aliases

Note that the length constraint applies only to the ARN. If you
specify only the function name, it is limited to 64 character in
length.

:enabled(Boolean)
—

Specifies whether AWS Lambda should actively poll the stream or not.
If disabled, AWS Lambda will not poll the stream.

:batch_size(Integer)
—

The maximum number of stream records that can be sent to your Lambda
function for a single invocation.

Updates the code for the specified Lambda function. This operation
must only be used on an existing Lambda function and cannot be used to
update the function configuration.

If you are using the versioning feature, note this API will always
update the $LATEST version of your Lambda function. For information
about the versioning feature, see AWS Lambda Function Versioning and
Aliases.

This operation requires permission for the lambda:UpdateFunctionCode
action.

You can specify a function name (for example, Thumbnail) or you can
specify Amazon Resource Name (ARN) of the function (for example,
arn:aws:lambda:us-west-2:account-id:function:ThumbNail). AWS Lambda
also allows you to specify a partial ARN (for example,
account-id:Thumbnail). Note that the length constraint applies only
to the ARN. If you specify only the function name, it is limited to 64
characters in length.

:zip_file(String, IO)
—

The contents of your zip file containing your deployment package. If
you are using the web API directly, the contents of the zip file must
be base64-encoded. If you are using the AWS SDKs or the AWS CLI, the
SDKs or CLI will do the encoding for you. For more information about
creating a .zip file, see Execution Permissions in the AWS
Lambda Developer Guide.

:s3_bucket(String)
—

Amazon S3 bucket name where the .zip file containing your deployment
package is stored. This bucket must reside in the same AWS Region
where you are creating the Lambda function.

:s3_key(String)
—

The Amazon S3 object (the deployment package) key name you want to
upload.

:s3_object_version(String)
—

The Amazon S3 object (the deployment package) version you want to
upload.

:publish(Boolean)
—

This boolean parameter can be used to request AWS Lambda to update the
Lambda function and publish a version as an atomic operation.

:dry_run(Boolean)
—

This boolean parameter can be used to test your request to AWS Lambda
to update the Lambda function and publish a version as an atomic
operation. It will do all necessary computation and validation of your
code but will not upload it or a publish a version. Each time this
operation is invoked, the CodeSha256 hash value the provided code
will also be computed and returned in the response.

Updates the configuration parameters for the specified Lambda function
by using the values provided in the request. You provide only the
parameters you want to change. This operation must only be used on an
existing Lambda function and cannot be used to update the function's
code.

If you are using the versioning feature, note this API will always
update the $LATEST version of your Lambda function. For information
about the versioning feature, see AWS Lambda Function Versioning and
Aliases.

This operation requires permission for the
lambda:UpdateFunctionConfiguration action.

You can specify a function name (for example, Thumbnail) or you can
specify Amazon Resource Name (ARN) of the function (for example,
arn:aws:lambda:us-west-2:account-id:function:ThumbNail). AWS Lambda
also allows you to specify a partial ARN (for example,
account-id:Thumbnail). Note that the length constraint applies only
to the ARN. If you specify only the function name, it is limited to 64
character in length.

:role(String)
—

The Amazon Resource Name (ARN) of the IAM role that Lambda will assume
when it executes your function.

:handler(String)
—

The function that Lambda calls to begin executing your function. For
Node.js, it is the module-name.export value in your function.

:description(String)
—

A short user-defined function description. AWS Lambda does not use
this value. Assign a meaningful description as you see fit.

:timeout(Integer)
—

The function execution time at which AWS Lambda should terminate the
function. Because the execution time has cost implications, we
recommend you set this value based on your expected execution time.
The default is 3 seconds.

:memory_size(Integer)
—

The amount of memory, in MB, your Lambda function is given. AWS Lambda
uses this memory size to infer the amount of CPU allocated to your
function. Your function use-case determines your CPU and memory
requirements. For example, a database operation might need less memory
compared to an image processing function. The default value is 128 MB.
The value must be a multiple of 64 MB.

If your Lambda function accesses resources in a VPC, you provide this
parameter identifying the list of security group IDs and subnet IDs.
These must belong to the same VPC. You must provide at least one
security group and one subnet ID.

To use the Python runtime v3.6, set the value to "python3.6". To use
the Python runtime v2.7, set the value to "python2.7". To use the
Node.js runtime v6.10, set the value to "nodejs6.10". To use the
Node.js runtime v4.3, set the value to "nodejs4.3". To use the
Python runtime v3.6, set the value to "python3.6".

Node v0.10.42 is currently marked as deprecated. You must migrate
existing functions to the newer Node.js runtime versions available on
AWS Lambda (nodejs4.3 or nodejs6.10) as soon as possible. You can
request a one-time extension until June 30, 2017 by going to the
Lambda console and following the instructions provided. Failure to do
so will result in an invalid parameter error being returned. Note that
you will have to follow this procedure for each region that contains
functions written in the Node v0.10.42 runtime.

The parent object that contains the target ARN (Amazon Resource Name)
of an Amazon SQS queue or Amazon SNS topic.

:kms_key_arn(String)
—

The Amazon Resource Name (ARN) of the KMS key used to encrypt your
function's environment variables. If you elect to use the AWS Lambda
default service key, pass in an empty string ("") for this
parameter.
